CROSS REFERENCE OF RELATED APPLICATION

The present application is a continuation application of PCT ApplicationNo. PCT/CN2019/080099 filed on Mar. 28, 2019, which claims a priority ofChinese patent application No. 201810301846.7 filed on Apr. 4, 2018,which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to the field of communicationstechnology, and in particular to a channel and signal transmissionmethod and a communication device.

BACKGROUND

The long term evolution (Long Term Evolution, LTE)/LTE-Advanced (LTE-A)and other wireless access technology standards are based onmultiple-input multiple-output (Multiple-Input Multiple-Output,MIMO)+orthogonal frequency division multiplexing (Orthogonal FrequencyDivision Multiplexing, OFDM) technology. The MIMO technology uses thespatial freedom obtained by the multi-antenna system to improve the peakrate and system spectrum utilization.

In the process of standardization development, the dimensions of MIMOtechnology continue to expand. In LTE Rel-8, up to 4 layers of MIMOtransmission can be supported. In the enhance multi-user multiple-inputmultiple-output (Multi-User Multiple-Input Multiple-Output, MU-MIMO)technology in Rel-9, the transmission mode (Transmission Mode, TM)-8MU-MIMO (Multi-User MIMO) transmission can support up to 4 downlink datalayers. In Rel-10, the single-user multiple-input multiple-output(Single-User MIMO, SU-MIMO) transmission capacity is extended to 8 datalayers at most.

The industry is further advancing the MIMO technology towardsthree-dimensional (Three Dimensions, 3D) and large-scale. At present,the 3rd generation partnership project (3rd Generation PartnershipProject, 3GPP) has completed the 3D channel modeling research project,and is carrying out the eFD-MIMO and New Radio (NR) MIMO research andstandardization work. It is foreseeable that in the future 5G mobilecommunication system, the MIMO technology with a larger-scale and moreantenna ports will be introduced.

Massive MIMO technology uses the large-scale antenna array, which cangreatly improve the system frequency band utilization efficiency andsupport a larger number of access users. Therefore, major researchorganizations regard massive MIMO technology as one of the mostpotential physical layer technologies in the next generation of mobilecommunication systems.

In the massive MIMO technology, if an all-digital array is used, themaximized spatial resolution and optimal MU-MIMO performance can beachieved, but this structure requires a large number ofdigital-to-analog (DA)/analog-to-digital (AD) conversion devices and alarge number of complete radio frequency-baseband processing channel,both equipment cost and baseband processing complexity will be a hugeburden.

In order to avoid the aforementioned implementation cost and equipmentcomplexity, the digital-analog hybrid beamforming technology came intobeing, that is, on the basis of the traditional digital domainbeamforming, near the front end of the antenna system, an additionallevel of beamforming is added to the radio frequency signal. The analogbeamforming can make the transmission signal and the channel achieve arelatively rough match in a relatively simple way. The dimension of theequivalent channel formed after analog beamforming is smaller than theactual number of antennas, so the subsequent required AD/DA conversiondevices, the number of digital channels, and the corresponding basebandprocessing complexity can be greatly reduced. The residual interferenceof the analog beamforming part can be processed again in the digitaldomain to ensure the quality of MU-MIMO transmission. Compared withall-digital beamforming, the digital-analog hybrid beamforming is acompromise between performance and complexity, and has a higherpractical prospect in systems with high frequency bands, large bandwidthor a large number of antennas.

In related art, at least two channels and signals are transmitted in theuplink or downlink. However, in high-frequency systems (communicationsystems in the frequency band above 6 GHz), the transmitter willdetermine the QCL information of these channels and signals according torelated art, such as spatial-time-frequency parameters of the channel orsignal indicated by TCI status, and the receiving end may perform areception according to these parameters. There are no clear rules forjudging whether at least two channels and signals can be multiplexed onthe same symbol, and how to multiplex them on the same symbol, so it ispossible that the base station and the terminal may inconsistentlyunderstand the relevant parameters of the transmitted channel or signal,resulting in an incorrect reception of the channel or signal.

DETAILED DESCRIPTION

Hereinafter, exemplary embodiments of the present disclosure will bedescribed in more detail with reference to the drawings. Althoughexemplary embodiments of the present disclosure are shown in thedrawings, it should be understood that the present disclosure can beimplemented in various forms and should not be limited by theembodiments set forth herein. On the contrary, these embodiments areprovided to enable a more thorough understanding of the presentdisclosure and to fully convey the scope of the present disclosure tothose skilled in the art.

The terms “first”, “second” in the specification and claims of thepresent disclosure are used to distinguish similar objects, and are notnecessarily used to describe a specific sequence or sequence. It shouldbe understood that the data used in this way can be interchanged underappropriate circumstances, so that the embodiments of the presentapplication described herein can be implemented in a sequence other thanthose illustrated or described herein, for example. In addition, theterms “including” and “having” and any variations of them are intendedto cover non-exclusive inclusions. For example, a process, method,system, product, or device that includes a series of steps or units isnot necessarily limited to the clearly listed steps or units, but mayinclude other steps or units that are not clearly listed or are inherentto these processes, methods, products, or equipment.

In the study of next-generation communication systems after 4G, theworking frequency band supported by the system is increased to above 6GHz, up to about 100 GHz. The high frequency band has relativelyabundant idle frequency resources, which can provide greater throughputfor data transmission. At present, 3GPP has completed the high-frequencychannel modeling work. The wavelength of the high-frequency signal isshort. Compared with the low frequency band, more antenna elements canbe arranged on the panel of the same size, and the beamformingtechnology is used to form beam with a stronger directivity and anarrower lobe. Therefore, combining large-scale antennas withhigh-frequency communications is also one of the future trends.

Regarding beam measurement and reporting (beam measurement and beamreporting), analog beamforming is a full-bandwidth transmission, andeach polarization direction element on the panel of each high-frequencyantenna array can only transmit the analog beam in a time-divisionmultiplexing manner. The beamforming weight of the analog beam isrealized by adjusting the parameters of the RF front-end phase shifterand other equipment.

At present, in academia and industry, the training of analog beamformingvectors is usually carried out by polling, that is, the array element ofeach polarization direction of each antenna panel sends the trainingsignal (that is, the candidate shaping vector) in turn at the appointedtime in a time-division multiplexing manner, the terminal feeds back thebeam report after a measuring the training signal, so that the networkside may use the training signal to implement the analog beamtransmission during the next service transmission. The content of thebeam report usually includes several optimal transmit beam identifiersand the measured received power of each transmit beam.

Regarding the beam indication mechanism, in related art, the networkside device configures correspondence between state and reference signal(Reference Signal, RS) and the transmission configuration indication(Transmission Configuration Indication, TCI) for the user equipment(User Equipment, UE) through a radio resource control (Radio ResourceControl, RRC) signaling.

When TCI is used for the Quasi-colocation (QCL) indication of thePhysical Downlink Control Channel (PDCCH), the network side deviceconfigures K TCI states (states) for each CORESET, when K>1 at thistime, a media access control (Media Access Control, MAC) control element(CE) indicates one TCI state. When K=1, no additional MAC CE signalingis required. When the UE monitors the CORESET, it uses the same TCIstate for all search spaces in the CORESET. The RS resource in the RSset corresponding to the TCI state (for example, periodic channel stateinformation reference signal (CSI reference signal, CSI-RS) resource,semi-persistent CSI-RS resource, SS block, etc.) and UE-specific PDCCHdemodulation reference signal (Demodulation Reference Signal, DMRS) portis spatial QCL. The UE may learn which receiving beam to use to receivethe PDCCH according to the TCI state.

When TCI is used for PDSCH QCL indication, the network activates 2^(N)TCI states, and then uses the N-bit TCI field of Downlink ControlInformation (DCI) to notify the TCI state. The RS resource in the RS setcorresponding to the TCI state and the DMRS port of the physicaldownlink shared channel (Physical Downlink Shared Channel, PDSCH) to bescheduled are QCL. The UE may learn which receiving beam to use toreceive the PDSCH according to the TCI state. For the presence orabsence of TCI field in DCI, when scheduling offset <=k (schedulingoffset refers to the time interval from when DCI is received to when DCIbecomes valid), the QCL of PDSCH uses the default TCI state, where thedefault TCI state is the TCI state of the CORESET with the smallest IDin the slot.

For the initial TCI states of the PDCCH and PDSCH, between the initialRRC configuration and the MAC CE-activated TCI states, the PDCCH DMRSand PDSCH DMRS and the initial access determined synchronization signalblock (Synchronization Signal Block, SSB) are spatial QCL.

When TCI is used for QCL indication of Physical Uplink Control Channel(PUCCH), a RRC signaling is used for PUCCH beam indication. The RRCparameter used is the physical uplink control channel spatialrelationship information (PUCCH-Spatial-relation-info). The RRCconfiguration is per PUCCH resource, and the configured PUCCH beaminformation is related to the SSB ID or CSI-RS resource indicator (CSI)or SRS Resource Indicator (SRI). When the PUCCH-Spatial-relation-infocontains multiple entries, the MAC-CE is used to indicate the spatialrelationship information (spatial relation information) between thePUCCH resource and one entry of the PUCCH-Spatial-relation-info. Whenthe PUCCH-Spatial-relation-info includes only one Spatial Relation InfoIE, the UE applies the configured Spatial Relation Info and does notneed to use MAC-CE.

When TCI is used for CSI-RS QCL indication, the source RS and target RScan be: SSB→periodic CSI-RS (Periodic CSI-RS, P-CSI-RS)/semi-persistentCSI-RS (Semi-Persistent CSI-RS, SP-CSI-RS), P-CSI-RS→P-CSI-RS,SSB/P-CSI-RS/SP-CSI-RS→aperiodic CSI-RS (Aperiodic CSI-RS) RS,AP-CSI-RS). There is no QCL between the two CSI-RSs by default. TheSP-CSI-RS is configured by RRC SP-CSI-RS resource(s), andactivated/deactivated by MAC-CE. When the MAC-CE activates theSP-CSI-RS, it also indicates the QCL of SP-CSI-RS. For AP-CSI-RS, theRRC configures the QCL of AP-CSI-RS resource and uses DCI to triggerAP-CSI-RS.

When TCI is used for the QCL indication of sounding reference signal(Sounding Reference Signal, SRS), the QCL is indicated by an SRSresource or Downlink (DL) RS, and the DL RS includes at least CSI-RS andSSB. When the target RS is P-SRS, the target RS is configured by a RRCsignaling. When the target RS is SP-SRS, the target RS is indicated bythe RRC+MAC-CE. When the target RS is AP-SRS, the target RS isconfigured by the RRC or RRC+MAC-CE and indicated by the DCI.

At least two channels and signals are transmitted in the uplink ordownlink. However, in high-frequency systems (communication systems inthe frequency band above 6 GHz), the transmitter will determine the QCLinformation of these channels and signals according to related art, suchas spatial-time-frequency parameters of the channel or signal indicatedby TCI status, and the receiving end may perform a reception accordingto these parameters. There are no clear rules for judging whether atleast two channels and signals can be multiplexed on the same symbol,and how to multiplex them on the same symbol, so it is possible that thebase station and the terminal may inconsistently understand the relevantparameters of the transmitted channel or signal, resulting in anincorrect reception of the channel or signal.

In view of the above issues, a channel and signal transmission methodand a communication device are provide in the embodiments of the presentdisclosure, which can make the communication device at the sending endand the receiving end have consistent understanding of the relevantparameters of the channel and signal to be transmitted, therebyrealizing the correct transmission of the channel and signal.
